In Chapter 12, Poem 27 of Attar's Mokhtar Nameh, the poet laments a life wasted in spiritual negligence. The poem contrasts the "enemy-self" (the carnal soul or nafs) with the "Friend" (the Divine). It expresses deep regret over a heart that spent its time indulging the lower self—metaphorically sleeping a hundred nights for the enemy—while failing to stay awake and keep vigil for even one night in devotion to the Friend.
